The eight major heavy metals in toys EU standards and Canadian standard methods

Introduction Where does the “poison” of children’s toys exist? Most of them are found in paint. Some domestic companies have two sets of standards for children’s toys. The export standards are very high and use non-toxic and harmless raw materials, while low-cost hazardous raw materials are used for domestic sales. Most of my country’s color toys have heavy metals tha...

The Importance of Measuring LED Chromaticity

Light-emitting diodes are not just a simple turn-on and turn-off mechanism. In addition to simply emitting a white light, LEDs also have the ability to emit thousands of shades. The characteristics of light color and intensity are called chromaticity, and this indicator is important to both LED manufacturers and consumers. Before the product goes on the market, the importance of measuring the chro...

How to use a salt spray test chamber to determine the corrosion resistance of LED lamps

Salt spray test is a kind of environmental reliability test, mainly used to test the corrosion resistance of metal materials of lamps. In order to verify whether the metal parts on the product will corrode when exposed to the atmosphere or other environments, the product can be placed in the use environment for a long enough time, such as a product life cycle. This is time-consuming and labor-inte...

Classification and test of waterproof grade of lamps

IP (International Protection) protection level is the dust and water protection level of the product shell specified by the International Electrical Association (IEC). The requirements for waterproof test are very simple, that is, to prevent the intrusion, penetration, penetration, inflow or overflow of water. The diameter of water molecules is about 0.4nm, and the capillary pores larger than this...

New ErP energy efficiency rating calculation method for LED lighting

Before calculating the ErP energy efficiency rating method, we must first determine whether the lamp under test is a directional light source or a non-directional light source. The judgment method is as follows: First, use the goniophotometer system to test the IES file of the tested luminaire. The directional lamp refers to the luminaire whose effective luminous flux is greater than 80% of the li...

How much do you know about plant growth lamps

LED plant growth lamp is an artificial light source that uses LED (light emitting diode) as the luminous body to meet the lighting conditions required for plant photosynthesis. Classified by type, it belongs to the third generation of plant supplement lamps. In the lack of daylight environment, this kind of lamp can act as daylight, so that plants can grow and develop normally or better. Light env...
